International administrative law represents a special (sub)discipline of administrative law, governing administrative relations with certain foreign element by a set of delimiting norms. The aim of these delimiting norms is to address those situations, where a foreign element (e.g. foreign acts, persons having immunities under international public law etc.) appears in the relations of administrative law.
In this respect, several thorny issues may appear. This article aims to address three of them.
Firstly, the question of applicable law will be analysed with respect to relations, where a foreign element appears. Secondly, the qualification problem with respect to foreign administrative acts will be addressed.
And thirdly, the article will tackle the issue of extraterritorial extensions of competences of domestic authorities abroad and will deal with the issue of applicable law in these situations.
